Nissan previews its electric vehicle platform

Nissan is suddenly hogging the green car news; after announcements about making batteries in the UK and Portugal, now the company has previewed its electric vehicle platform in a hatchback body.

Nissan says its dedicated EV platform is comprised of a highly rigid body, high-performance motor, compact lithium-ion battery with high power output and energy capacity, delivering outstanding driving performance and safety, while offering a quiet and peaceful driving experience – a unique feature of a fully-electric drivetrain.

The in-house developed electric motor delivers 80kW/280Nm for high response and powerful acceleration. Nissan’s unique motor control also contributes to the vehicle’s seamless acceleration.

The 24kWh laminated compact lithium-ion battery pack is placed under the vehicle floor for more efficient packaging, without compromising cabin or cargo space. The battery layout also allows smooth underfloor airflow which helps reduce drag. Additionally, the regenerative brake system employed to recharge the battery during deceleration and braking extends the driving range to more than 160km under a full charge.

High durability is achieved by employing an additional frame for the battery pack to significantly improve the rigidity of the platform. The combination of a high rigidity platform and electric powertrain minimises vibration and noise to produce a quiet drive.

Nissan has also developed a sophisticated IT system for its zero-emission EVs, connecting the vehicle’s on-board transmitting unit to a global data centre to support EV driving 24 hours 7 days a week.

Nissan’s EV will have a maximum range display – with a touch of a button, the navigation map shows the driving radius within range under the current state of charge and the system can calculate if the vehicle is within range of a pre-set destination.

In addition, the navigation system points out the latest information on available charging stations within the current driving range, and detailed information for each charging station will also be displayed.

A timer function enables the air-conditioner or battery charging to begin at a specified time. The air-conditioner can be pre-set while the vehicle is plugged-in to cool the cabin to a desirable temperature before driving begins, without taxing the vehicle’s battery. Meanwhile, the battery charging can be set to start at a specified time at night to benefit from more favourable electricity rates.

The driver can monitor the state-of-charge of the EV via an online website and a cellular phone. For example, when the battery is fully charged, a message alert is sent to the cellular phone. Additional remote control functions range from switching the charging system ON/OFF or setting the air-conditioner timer.

Although Nissan’s photo shows the EV platform within a hatchback body, this is not how the 2010 electric vehicle will look. It will have a unique design and body and Nissan plans to unveil the design of the production EV at its new Global Headquarters Opening in Yokohama on August 2nd. A Nissan Zero-emission Website (
